Stunning exceptional-plus 53.33ct round tanzanite measuring 23.16x23.42x14.73mm. From our esteemed Founders' Collection this tanzanite is a must-have for the serious tanzanite collector. Our buyer Jay Boyle recently returned from a buying trip saying he just cannot find the same color he could find seven or eight years ago. This particular tanzanite is from a large buy we did several years ago and has that rich, old mine color. Beautiful Portuguese cutting creates a seemingly endless display of facets in this flawless tanzanite. Comes with appraisal listing an approximate replacement cost of $133,350.00. This treasure sold during the show, but we have many other rare tanzanite gemstones in The Vault.
